Envoy on BNA to MIA sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 346 flights. The strongest carrier on the route with a full sample, American Airlines, flew 1,321 at 77.3% on time.

The national on-time rate over the same period is 77.6%, so Envoy on BNA to MIA runs 4 points behind the country as a whole. Across a thousand flights that is about 44 extra late arrivals.

These figures cover 346 flights between July 2025 and June 2026. Beyond the headline rate, 10.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Envoy against every carrier on BNA to MIA

Envoy flew 346 of the 2,504 flights on BNA to MIA, about 14% of it. Its 73.2% on time is 2 points worse than the route as a whole, which runs 75.1%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from American at 77.3% to Spirit at 69.8%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 5 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

No carrier stands out. American tops the table at 77.3%, 5 points clear of the bottom, which is inside the range this kind of sample moves year to year.

Departure window

When Envoy runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 13 points, against 5 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

8am–11am49 flights79.6%

5pm–8pm150 flights67.1%

Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 79.6% of the time, against 67.1% for the evening window. That is 13 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 150 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 73.2% on time across 346 flights.

Envoy on BNA to MIA did not run the same all year. Its best quarter was Jul–Sep 2025 at 82.4% on time and its weakest Jan–Mar 2026 at 65.6%, a swing of 17 points on roughly 87 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Wednesday is the strongest day at 85.1% on time and Sunday the weakest at 60.8%. 24 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Envoy runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 6,164 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Extreme weather
3%

62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,164 reported delay minutes here, that single category outweighs weather by 19 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,164 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 79.6% on time here.

Cancellations sit at 1.45% against a national 1.81%, which is ordinary. Diversions add another 0.29%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.6% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 806 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 90.3% on time across 344 flights, 17 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 17 points of difference.

One caution: this is a thin sample. 346 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking Envoy on BNA to MIA

Put together: treat all of this as provisional. 346 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 73.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 340 completed flights over 12 months sit behind that.
